Menthol crystals dissolve readily into alcohol or essential oils, and they can be dissolved into water or oil at their melting point of 111.ºF. Menthol crystals are cooling, refreshing, and have a pleasantly strong minty aroma. They are often used in cosmetics, salves, balms, medicated creams, foot sprays, pain relief, shampoos, conditioners, liniments, shaving creams, compresses, medicated oils, cooling gels and lately in shower steamers. Since Menthol crystals are so concentrated, only a very small amount is needed within products.
Menthol also has anti-fungal and anti-bacteria properties.

Shower sinus steamer recipe
With gloves, dissolve the menthol crystals in the alcohol. Add more if required. Combine all your remaining dry ingredients in a bowl. Add the colour dye if using. Use a whisk to remove all lumps. The mixture can be sifted. Be aware that both menthol and eucalyptus are very pungent so use carefully.
Add the oil, eucalyptus and the menthol mixture and combine. Add the water and combine until the mixture sticks together like dry sand in your hand. Pack into the ice cube tray tightly. Let sit for 24 hours. The next day turn the tray over and lightly tap until steamers come out. Store and label in an airtight container for later use.
Place on the shower floor near the spray of the shower. Be prepared for an intense sinus clearing.
